In a sweeping move that reshapes the global legal landscape, Ashurst LLP of the U.K. and Perkins Coie LLP of the U.S. announced Monday that they will unite to form a new $2.7 billion legal titan. The partnership—one of the most significant transatlantic tie-ups in recent years—creates Ashurst Perkins Coie, a top-20 global firm boasting nearly 3,000 lawyers.
Like two continents drifting together over centuries, the merger brings decades of expertise crashing into alignment, generating a force felt across the world’s most competitive legal markets.
A New Global Giant With 52 Offices
The newly formed Ashurst Perkins Coie will operate from 52 offices across 23 countries, anchoring itself with flagship hubs in Seattle, London, Sydney and New York. Additional specialist teams will remain in major financial centers such as Brussels, Dubai, Frankfurt, Hong Kong and Paris—a footprint designed to rival the world’s most expansive firms.
The combined practice will zero in on core high-growth sectors: technology, energy and infrastructure, and financial services.
